IOWN Energy completed the sale of the Roccasecca project in Boulder City, Nevada, on behalf of its client, Eolus North America. The transaction was an all-cash sale involving the transfer of all shares of the project special purpose vehicle.
The deal included $290 million in senior secured credit facilities to support construction and operations. Zions Bancorporation, Société Générale, Intesa Sanpaolo, and Bayerische Landesbank served as coordinating lead arrangers for the financing.
The Roccasecca project has a 15-year tolling agreement in place. It is currently under construction and is expected to reach commercial operation in 2026.
The project enters a U.S. market that installed 18.9 GW and 51 GWh of capacity in 2025, representing a 52% increase in installations compared to 2024 levels according to Wood Mackenzie. Utility-scale storage installations reached 16 GW for the full year, representing the vast majority of new capacity.
While lithium-ion remains the primary technology for such projects, alternative chemistries like sodium-ion and flow batteries are increasingly viewed as bankable solutions to mitigate supply risks.
Grid-scale energy storage regional diversification is accelerating. While California and Texas remain leaders, utility-scale growth occurred in 22 states throughout 2025. This expansion aligns with a Wood Mackenzie projection of a 250% increase in storage capacity between 2026 and 2031 compared to the previous five-year period.
Utility-scale storage is projected to grow at an average rate of 16% per year. This growth is supported by federal incentives, load growth from data centers, and increasing demand for peak power.
Future growth remains sensitive to federal guidance on Foreign Entities of Concern (FEOC). Wood Mackenzie analysis suggests 28 GW of upside if trade barriers ease, while stricter guidance could result in 17% less capacity than current base-case projections.
Sweeping import tariffs and the One Big Beautiful Bill Act (OBBBA) created headwinds in 2025. Developers continue to navigate these policy shifts by seeking safe harboring deadlines to maintain project timelines.
IOWN Energy has facilitated over 1 GW of renewable energy project sales since 2021. The firm focuses on development and financing for wind, solar, and standalone storage across the U.S. and Mexico.
